Location Information Based Service TRIZ Cases
- Personal Device Networks Using Co-Location for User Authentication
Co-located smartphones and tablets authenticate users wirelessly, avoiding specialized readers and cumbersome sign-in procedures.
- Cellular Device Characterization Through Synchronized Scanning
Synchronizing base-station communication slots with frequency scanning helps locate equipment detect cellular devices across changing bands.
- Internet-Connected Household Identification Using IP Stability Signals
Dynamic and shared IP addresses hinder household measurement; activity, assignment age, and registry checks improve identification accuracy.
- Signaling Firewall Location Validation Through Call Intelligence
Correlate call history with location updates to strengthen firewall validation.
- Wireless Phone Isolation and Location Using TDD Uplink Filtering
A narrowed downlink and filtered uplink help reduce TDD interference while a power detection device estimates phone location.
- Wireless Ranging Signal Sequencing for Channel-Adaptive Accuracy
Channel-aware signal sequencing improves ranging accuracy across wireless links.
- Passive BLE Signal Analysis for Accurate Device Presence Detection
BLE advertising packets and MAC analysis count unique devices, reducing false alarms while avoiding invasive surveillance.
- Physical-Address-Linked Electronic Accounts for Secure Targeted Messaging
Geolocation, verification, and separate location and user identifiers stabilize accounts while enabling targeted messaging.
- GSM User Allocation Using Timing-Advance Location Sectors
This case uses timing-advance measurements and POI probabilities to improve GSM user location estimates from cell events.
- Dynamic VR Navigation Mapping with Hybrid User and Drone Data
User routes, VR constructs, drone data, and wireframes generate personalized maps that improve navigation in evolving VR spaces.
- Cell Tower Locationing to Extend Asset Tracker Battery Life
A wireless tracker uses tower identifiers and stored coordinates to locate transported assets while reducing GPS-related battery demand.
- Adaptive Location Determination with Hybrid Indoor Positioning
A server combines GPS, Wi-Fi, cellular, and inertial inputs to resolve indoor positioning gaps and display mobile locations.
- Mobile Network Presence Estimation Across Sub-Cell Zones
Uniform cell-level assumptions can misestimate local presence; this method weights terminal positions across zones for finer mapping.
- Bluetooth Tag Timing and Tracking for Sporting Events Beyond Cell Coverage
BLE tags with adjustable transmission support timing, participant tracking, and mapped data collection where cell service is unavailable.
